Backyard pools are fun in and of themselves — but when this dad came up with a way to turn the standard backyard pool into a wave pool, things got more fun than ever. It’s a simple concept, really: Push water down forcefully, and it has to surge back up in the form of some pretty epic waves. To create the waves, he used a small boogie board and a whole lot of strength. We’d like to personally thank this dad for teaching us how to upgrade our backyard pools this summer.
